Overview:

Altronix models PT724A/DPT724A/PT724AE are extremely versatile 24 Hour 365 Day Event Timers designed

to support a wide range of applications. Such applications include: Home and Building Automation, Security,

Access Control, Lighting Control, Etc. PT724A/DPT724A/PT724AE are equipped with an independently con-

trolled form “C” relay contact that provides many latching and/or momentary operations during a program sched-

ule of your choice. The EE prom memory allows for programming of unit prior to/or during field installation.

Events may be set for single or multiple operations on a daily and/or weekly schedule. The block programming

feature enables repeating an event on any combination of consecutive days. PT724A/DPT724A/PT724AE will

compensate for daylight savings time if desired. Individually selected holiday exceptions can be programmed to

override regularly scheduled events.

Installation Instructions:

1. Mount PT724A/PT724AE/DPT724A in desired location.

Carefully Review:

Basic Operation (pg. 3)

Terminal Identification Table (pg. 3)

Push Button Layout and Description (pg. 4)

Programming Instructions (pg. 4-6)

2. Connect 12 to 24 volts AC or DC to terminals marked [+ DC – / ~ AC ~].

When using DC carefully observe polarity.

3. Connect 12VDC battery (optional) to terminals marked [+ BAT – / 12VDC].

4. Insert lithium battery (optional/not included. Order part LB2032) in battery holder (Fig. 1, pg. 3) with

the + positive side facing up.

5. Connect devices to be controlled to dry outputs marked [NO, C, NC].

Note: It is important when connecting DC powered electromechanical devices such as Mag Locks, Electric

Strikes, Bells, Relays, etc. to install a catch diode across the pos (+) and neg (–) terminals of the device.

Connect diode as close to the device as possible with the banded side facing the pos (+) terminal.

This will reduce the possibility of interference.

6. Program clock and desired event schedule (see programming instructions pg. 4-6).

Basic Operation:

PT724A/PT724AE/DPT724A controls an independently operated dry form “C” relay output. Relay can be

programmed to: turn on (latch), turn off (release latch) or pulse (momentary toggle) at a specified time and day

(this is referred to as an event). Events are programmed via the push buttons and LCD display. Events may be

programmed to occur on any day of the week at any time. In addition, events may be repeated at a specific time

on two (2) or more consecutive days (i.e. M-F, Sun-Th, etc). Multiple combinations of individual and block

events may be programmed. Holiday exceptions are individually selected by date and will override all regularly

scheduled events.

Output Relay Modes:

Mode Status

Relay OFF

De-energizes the relay until a relay ON event is detected.

Relay ON

Energizes the relay until a relay OFF event is detected.

Disable

Used to cancel an existing programmed event.

Pulse

Momentarily energizes the relay for a selectable time period of 1 sec. to 15 secs.

Time is displayed in 24 hr. military format.

Terminal Identification Table:

Terminal Legend Function/Description

NO, C, NC

Dry Contact output used to switch controlled devices. When these relays are energized

(ON) the NC and C terminals are open and the NO and C terminals are closed. When

this relay is de-energized (Off) the NC and C terminals are closed and the NO and C

terminals are open.

AC or DC Input 12 to 24 volt. When using DC carefully observe polarity

+ BAT –

12VDC

12VDC stand-by battery input (battery leads provided).

When this terminal is connected to DC neg. (–) the “First Man in” feature is enabled. The

relay will remain in its present position until this connection is terminated. At that time

the relay will resume normal operation and latest scheduled events will occur.
